A very good price for LED replacement bulbs. RRP is supposedly £9.99, but you'd usually expect to pay £5-£6 for something similar on Amazon.
Description from site:
3.5W G9 LED Replacement Lamps Cylinder Shape Warm White
• Low power LED replacement for traditional Halogen G9 lamps
• Cylinder configuration for wide angle illumination
• Long life LEDs rated to 35,000 hour lifespan
• 230V AC mains powered
At 285 lumen output, they're roughly equivalent to a 25w halogen.
There's a few other LED bulbs also for £1 so worth a look. Free collection from local store.
